The Contros undersea chemical analyzers offer
new capabilities in underwater CO2 methane, PAH Offshore oil and gas exploration, environmental sciences
and protection, ocean acidification and oceanographic research now have powerful new tools for
chemical analysis from the surface to 6000 meters. HydroC™ sensors
can independently deployed or operated from ROVs and AUVs.

Symphotic TII Corporation is pleased to offer
two versions of the HydroC™ CO2
Analyzer: the HydroC™ CO2
FT, a flow through system for laboratory and onboard vessel pCO2
determinations, and the HydroC CO2 submersible analyzer with an
integrated flow pump for faster response times.

Our newest product is the HydroFlash™ O2 sensor:
a high performance "Optode" (optical sensor in an electrode sized package.)

The
ControsTM HydroC FT Flow Through CO2 Sensor

The
ControsTM HydroC Submersible CO2 Sensor with

flow-head

The HydroC™/CO2 is used to measure pCO2
in water and is available either as a submersible sensor or a
laboratory or on-board modular analyzer.

The Chemistry of Ocean Acidification

The Improved HydroC™/PAH detects and
measures polyaromatic hydrocarbons for environmental monitoring, and
analytical chemistry in limnological and oceanographic research. It also
has applications in environmental remediation after oil spills.
This system is compact, sensitive, reliable, and simple to deploy.

Sources of PAH in Seawater can be natural or
anthropogenic

The ControsTM
HydroC FT Flow Through CH4 Sensor

The HydroC™/CH4
is used to measure CH4
in water and is available either as a submersible sensor or a
laboratory or on-board modular analyzer.

Optode sensor:

Powerful analytical capability in a compact
sensor

:

The optode is an optical sensor in compact,
electrode sized housing. This sensor determines dissolved
oxygen by fluorescence quenching: oxygen diffuses into a
fluorescent membrane coating on the surface of an optical
window. The coating is illuminated from the rear and the
fluorescence is measured. The measured fluorescence is
inversely proportional to the dissolved oxygen concentration.
This technique gives an elegant, rapid and robust method for
dissolved oxygen determination. Both temperature and
percent saturation (0 to 200%) are time-stamped and stored on
board for later recall, or can be accessed in real time through
an RS-232 interface.
